Find the price customers will buy at.

Measure purchase intent at several prices to see how demand changes, where customers begin to drop away, and which price offers the strongest revenue potential.

Pricing requires demand evidence

01The best-selling price is being chosen without demand evidence.
02The demand impact of a price increase is uncertain.
03The point where demand begins to fall is unclear.
04A single price can hide meaningful differences between customer groups.

Gabor-Granger shows how demand changes at each price and where revenue potential is strongest.

FROM RESPONSES TO RESULTS

Demand and revenue by price

Every figure below comes from one real example study — 30 respondents rating purchase intent at seven price points, computed by the same engine your own survey runs on.

Purchase intent by price

The same respondent answers at each price step, allowing demand to be compared within respondents across prices.

Study design$5 — $149
Respondents30
Price steps7
Price range$5 — $149
Revenue-maximising$69
Intent there46.7%
Elastic from$69 → $99

Each respondent answers the same product at every price step, so the curve is within-person.

Demand curve

The curve shows the share of respondents willing to buy at each tested price.

Intent by price7 steps
$5$9$19$39$69$99$149
Interpretation
Intent runs 78% at $5 down to 10% at $149; the gold point is the revenue optimum.

Revenue-maximizing price

Multiplying price by purchase intent produces a revenue index and identifies the price with the highest revenue potential.

Revenue index = price × intent rate.

Price increase threshold

Elasticity per interval shows where demand starts falling faster than price rises — the ceiling for any increase.

Price elasticity|e| ≥ 1
$5 → $90.60inelastic
$9 → $190.60inelastic
$19 → $39−0.40inelastic
$39 → $690.20inelastic

Past |e| ≥ 1 a price rise loses more volume than it gains in margin.

Reasons behind price decisions

Optional follow-up questions explain perceived value, current spending, and the conditions that would encourage switching.
